The dielectric strength test of transformer oil is typically performed using a testing device known as a dielectric strength tester or voltage withstand tester. In this process, a standardized sample of the oil is placed between two electrodes in a test cell. The tester gradually increases the voltage applied across these electrodes while monitoring the voltage at which the oil breaks down or conducts electricity. This breakdown voltage is crucial for assessing the oil’s insulating properties and is indicative of its quality. Globecore offers specialized equipment for this testing, ensuring accurate and reliable measurements that adhere to industry standards, vital for maintaining the integrity and safety of transformers. Proper dielectric strength testing is essential in determining the effectiveness of transformer oil in insulating and protecting electrical components against short circuits and failures.
